So, the insurance company totalled my truck although the visual damege doesn't justify it. I currently plan to buy it back and fix it. I'm looking for an engine. The block (53) is cracked and I think this is a good time to replace it. So, I'm looking for suggestions and sources for a used or rebuilt motor. Or should I go with a new short block? I don't know how much they're going to offer me yet but want to explore my options before then. Thanks
